Be it known that i, salaam rims,

a subjectof the Kingdom of Great Britain,'

' residing at New York, in the county and of which the following is aspeciication.

.State of New York, have inventedcertain new" and useful Improvementsv in Cameras,

This invention has more particular refer- ,ence-to cameras of the type in which a conrality of pictures, the strip being advancedV as' desired, 'to bring successive portions thereof .into juxtaposition with the. lens; .'.The invention relates to the film strip ma' tinuous 'strip of sensitized material, commonly called a film strip or Elm roll, is adapted to receive the impressions for a plunipulating means, having 'no reference to themechanism for making the photographic impression thereon. v

Heretofore in cameras of this type, it hasv been necessary, if waste cfa portion of the `film strip' is to be avoided, to waituntll the full number. of impressions have been made lon the film striplhlereinafter generally referred to"asthe before' it was possible to develop and print any individual picture,

this vbeing often inconvenient.

' Aoped and printed, when desired, without any It is an object of this mventionto provide a means wherebyl such portion or portions of ave been exposed to receive the photographic impression, may be -develwaste oftheunexposed portions of the film.

A further object is to provide ameans whereby the exposed portion ofthe Elm may v.be separated from the unexp'osed portion and removed, and the unexposed portion advanced again as desired into relation with the lens. Another object is to provide a destruction and easyoperation. Al5

In the following description, the portion'v of the film lwhich has been exposed tov receive the photographic impression is referred to?. generally as the ewosed portion of the film, the remainder being .called the unexposed portion.l -To facilitate understanding the following description, the embodiment of the invention here shown. may

be said to be divided finto'three general parts or devices, which may he enumerated briefly as follows: A means for gripping and holding in proper position, the 'severed end of the uneXposed portion ofthe film; a means for severing the exposed portionr of the lilm from the unexposed portion' of th'e ilm; a

Vmeans whereby the unexposed'portion of thev jlil'm may be again operatively engaged by the .lm.'advancing-'device. 1

A s here illustrated, l'have embodied my invention in,or applied it to', a .camera of ordinary construction, the casing vivherhf is vindicated generally by the reference numeral 1,'-thi's camera having at-o posite ends, the

of which the roll of unexposed film is mounted in' the usual manner, while my invention is in the form of a compact, detachable de-- vice mounted in the opposite spool chamber 3..

Screwed into a threaded opening in one of the end walls of the spool chamber 3, isa head 6 which may have a milled flange 7 topermit'of easy rotation. rlhis head forms one end ofthe device for holding in proper position the severed end of the fil-m, the opposite end of such device being in the form of a flanged disk or head 8,

open toward the rear of the chamber 3, into supported in the other wall 5 of the spool chamber 3. These heads 6 and.v 8 are connected by a cylindervmade up of two longitudinally divided halves 9 and-10, arranged to have relative "movement' toward and away from one another to constitute the film engaging jaws. As here shown the part 10 is fixed to the heads 6 and 8, while the part 9 constitutes a clamping jaw and is fixed upon a hinge pintle. 11 rotatably supported at opposite ends in the heads 6 and 8, such pintle being rotatable 'to swing the part 9 by suitable means as the yoke shaped handle 12 hinged upon the ,projecting end of the intle and adapted to engage a pin 13 to hold) the part 9 in either open or closed position, as desired. As will be seen the hinge 11 is so disposed that the jaws which the film, indicated by the numeral l5, is introduced in a well known manner through the slot v16 and over the roller 17.

. Normally these jaws are open to permit of the lm passing freely therethrough, to wind upon the 'receiving spool.

Carried within this cylinder is the film severing means which, as heremshown, comprises a pair o f cooperating knives 25 and' 26, formed on the edges of a pair of semicylindrical members 27 and 28, the knife 25 being a stationary knife and the knife 26 being movable, the semi-cylindrical member 27 being here'shown as fixed upon a hinge pintle 29 locatedadjacent the pintle 11 and rotatably supported at its opposite ends in a pair of heads 30 and 31, the first of 4which is screwed into a threaded( opening in the head 6, the other beingI freely supported by the flanged disk8. Upon the projecting-end of. thisl pintle 29 is a yoke heads 30 and 31 at the opposite edge to that longitudinally into a pair of gripping jaws renacer `carrying the knife 25, the 'edge carrying such knife being free. The purpose of this arrangement will be pointed out later.

lfteferrin now to the means by which the film is a vanced, the winding spool is mounted coneentrically within the cylindrical gripping and cutting devices just described being supported at its ends in the heads 30 and 31. This winding spool is split 5 35 and 36, hinged at the circumference of i? the spool upon a rod 37, supported by the spool ends 38, and whichr are shown as normally pressed together by the spring39 and provided with the pins or teeth 40. rll`he spool ends 38 have fixed thereto trunnions 41, by which the spool is supported in the heads 30 and 31. These trinnions are hollow and rotatably support a rod 42 which passes axially through the spool between the jaws 35 vand 36, and is provided with cam members 43 which, when the rod is rotated in a directionopposite to that in which the spool4 is rotated to windl the film thereon, engage suitable coacting surfaces 44 on the interior of the'jaws to force the latter apart so as to permit insertion or Withdrawal of the film. rlhe rod 42 may -be rotated by means of a handle 42 similar to the handles 12 and 32 on the end thereof. Any suitable means may be provided by which the spoolis caused to rotate with thev rod, instead of the latter separating the jaws, when the rod is rotated in an opposite or winding direction. As here shownv one of the cams 43 engages with the hinge member of'one of the jaws, as indicatedin Fig. 7. ln the normal winding position of thespool, backward rotation or rotation in an unwinding 'direction of the rod, is prevented m5 b`y any suitable means, such as the pawl 45 on the head E30-engaging aratchet wheel 46 on the rod 42, it being thus impossible tov either unwind the film from the spool, or to open the spool jaws, when the spool is in lll@ normal position.

ln'order to enable the unexposed portion of the film remaining in the camera, to be.

again secured to the spool after the exposed portion has been severed therefrom by the 115 knives 25 and 26, as will be pointed out more fully later, ll provide a means for again operatively connecting the portion of the film remaining in the camera to the winding spool. 1n the present embodiment of my in- 120 vention, the spool is'ad'apted to be moved bodily toward the holding members 9 and 10 and grip the edge portion 154 of the film which projects inwardly from the positioning jaws after the film has been severed. VTo this end the spool trunnions bear in slots 50 in the heads 30 and 31, such slots extending rearwardly in a line intersectingthe meeting line of the positioning jaws. These slots each have a portion thereof narrowed/13o ice 'l as at 51 to receive -attened portions on ends of the slots 50. As here shown a pair.

of springs 53 (`Fig.12) having curved ends fitting the vrounded portions of 'the trunnions are located at opposite sides ofeach` of the slots 5 0, these springs being of sufcient strength toresist any pull on' spool fdue to-the winding of' the ilm thereon, but

not-of sucient strength to preventthe trunnions being pushed into the s1ots50. If desired, these springs may be `made double 'ended as shown, to engage the spool trunnion's` at both ends of the slots. Suitable means are preferably provided whereby when one end of the spool is moved, the other end thereof will be caused to move in unison therewith. I have here shown a' pair of bell crank levers 54 and` 55l mounted in slots 56 and 57 in the heads 30 and 3.1, and

in operative connection -by-therod or. link 58 connected to one ar'm of each. The oppof.

the slots, the spool ends through-the head 30, adjacent suchp site arm' of each bell crank lever 4is connected to the trunnions 41 by links 59 and, 60 loosely encircling the latter. To prevent access-of light to the interior of the detachable casing comprising` the' parts 27, 28, -30 and 31', a plate 61 may be .loosely mounted on the` end of theV spool trunnion, which project atean in position to cover the slot 50, beiny lsuitably guided, as by the slots 62 therein en.

gaging pins 63 on the head 30. The outer face of the trunnion slot in the head 31 may be permanently closed, as indicated'at 64. To accommodate movement ofthe spool in 38 may be cut away as shown' at 65.'

.In Figs. 14 and 15 have shown a modiied form of spool provided with means the jaws'35 and 36 may be posi-A tively orced together. In this. case the rod whereb 42 is separated into a'v pair of rods 65 and 66, whichfare disposed in cam lslots 67 and- Rotation of the rod 42 in'- one direction will' separate the jaws-while upon movement in theopposite -.direction,

68 in the jaws.

the rods 65 and 66 will engage the inner -surfaces of the cam slots 67 and 68 andso assist the spring 39 in forcing the teeth 40 through the end of thel film..

' The manner vof operatlon 'iis' asl lfollowsz.. The filmstrip is insemdfin the .camera illthe usual 'manner beingrotatably `mountedfV ber 2, and the-end thereof'v brought upjinto'the chamber The han-12 in the spool ch dles\ 12.and`` 32-havingben. rotated to pro-.

The spool is then I moved rearwardly in the slots, the springs 53 yielding.v When the "spool 'has been moved into the slots, the ratchet wheel 46 disengages from the pawl 45, thus permitting rotationof the handle 42` in a backward direction, while the spool as a whole`,1` j 1s prevented from rotation by the engagei5 mentof the attened trunnion portions 52/:1

withthe'sides of the narrowed portions 51 ff of. the slots 50. vThe handle 42. is n ow rotated to cause the cams 43 to separate the jaws 35 and 36'.v The end ofthe lm may4 then be introduced by hand between the jaws and the handle 42f rotated to.allow the spring 39 to'closethe jaws .upon` the film. The spoolv is then` moved b ack to its wind-v ing position and. the film may be wound-s5 Athereon as portions thereof are successively exposed, in the usual manner. If it isde. sired to develop any exposed portion 'of the film before the entire film has been exposed, the handle12 is rotated to close the' member 9 `down upon the member 10, the ilm being gripped as shown betwnsuch members. The handle Q32 is then rotated to cause `the knife 26 .to close upon the knife 25 and sever .the portionpf the lilm upon the spool from.

the remainder. By unscrewing the head 30-V from the head 6, .the spool with its i'nclosing" casing, made up of parts 27, V28, 30, 31,' may; be removed from the camerawithout expo`v sure of the film to the light. .The head 30 .may be provided' with suitable projections to facilitate rotation or the handles 32 and 42` may*l be used .asialneans to' grasp the head. The spool and casing' may again b e inserted in thecameraafter Aremoval of the film therefrom, or'a second spool and casing may be provided to be immediately inserted` t* inplace.` Todo this, the head 30 is screwedagain into the. head 6,` the-knives 25 and 26v are separated, andthe .spool is moved into then pushedrearwardly .to the end ofthe slots, in which position the jaws extend over the end-portion 15 ofthe ilm',' which' pro-A jects inwardly -from the1gripping"members the spool .is moved tothe v'end of .the
